 specifically accessing the “tasks” collection on any rootTask object
 (which according to the omnifocus applescript dictionary is present)
 causes this crash. Accessing a collection that is actually not there (like
 the error message suggests) only yields a standard ruby NoMethodError:

 {{{
 untitled:7:in `<main>': undefined method `wurst' for
 #<OmniFocusTask:0x400eefb40> (NoMethodError)
 /Users/gerrit/Library/Application
 Support/TextMate/Bundles/Ruby.tmbundle/Support/RubyMate/catch_exception.rb:14:in
 `block': not opened for writing (IOError)

 }}}
